Embodiment Construction

[0036] The core of the method for broadcasting the system information of the adjacent cell and the handover device of the present invention are: the network side of the local cell broadcasts and sends the relevant information about the frequency division of the primary subcarrier and secondary subcarrier of the adjacent cell to the user equipment of the local cell, so that the user Based on the information it receives, the device can perform corresponding measurements, calculations, and reports on the primary subcarriers and secondary subcarriers of adjacent cells, so that the network side can implement the cell handover process based on the information reported by the user equipment, enabling soft frequency reuse The cell switching process in the technology is realizable, thus perfecting the soft frequency reuse technology.

[0037] The technical solution provided by the present invention will be further described below based on the core idea of ​​the present invention.

Abstract

The invention relates to a method for broadcasting the nearby region system information of wireless communication system and relative device, wherein it is characterized in that: in the wireless communication system, the local region broadcasts the information relative to the main sub carrier wave and auxiliary sub carrier wave distribution to the user device of local region. The invention can make the network obtain the condition of main and auxiliary sub carrier waves of nearby region, to realize the region switch in soft frequency multiplex technique. And the invention provides several methods to represent the relative information of main and auxiliary carrier waves of nearby region, and reduce the bit of nearby region system information most, to realize the soft frequency multiplex technique.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for broadcasting system information of adjacent cells in a wireless communication system. Background technique [0002] Since the 1990s, multi-carrier technology has become a hot technology in broadband wireless communication. Its basic idea is to divide a broadband carrier into multiple sub-carriers and transmit data on multiple sub-carriers simultaneously. In most system applications, sub-carriers The width of is smaller than the coherent bandwidth of the channel, so that on the frequency selective channel, the fading on each subcarrier is flat fading, which reduces the interference between symbols, and does not require complex channel equalization, which is suitable for high-speed data transmission. [0003] There are many forms of multi-carrier technology, such as Orthogonal Frequency Division Multiplexing (OFDM), Multi-Carrier CDMA (MC-CDMA)...
